Hi All.
I used to use 3 1/8 and 1 5/8 copper transmission line in 20 ft lengths for ground systems at broadcast stations. Was very effective. Installed at a 2000ft tower which use to have a lot of damage due to lightning. We buried 40 lengths in a circle about 30 ft from the tower base. Connected them together with additional lengths of transmission line. Problem solved.

I know skin effect plays a big role in lightening since its mainly RF, what do you think about the idea? Cheers, Jesse
